'anticryptically' originates from the combining form 'anti-' (from Greek) + 'cryptic' (ultimately from Greek 'kryptos' meaning 'hidden'), where 'anti-' meant 'against, opposite' and 'kryptos' meant 'hidden'.

'cryptic' comes from Greek 'kryptikos' (from 'kryptos'), passed into Late Latin/Medieval Latin as 'crypticus' and into English as 'cryptic'; 'anti-' was attached to form 'anticryptic' and then the adverb 'anticryptically' was created by adding the adverbial suffix '-ally'.

Initially, elements signified 'against being hidden' (i.e., opposed to concealment); over time the combined form came to mean simply 'not cryptic' or 'clear/open', and the adverb now means 'in a clear or non-hidden manner'.
